Wipe your device to delete your data

Before you wipe your BlackBerry device, consider backing up your data on a computer. A security
wipe is designed to permanently delete your data so it can't be recovered. This
includes email accounts, downloaded apps, media files, documents, browser bookmarks,
and settings.

On the home screen, swipe down from the top of the
screen.

Tap Settings > Security and Privacy > Security
Wipe.

Type blackberry.

Tap Delete Data.

When the security wipe is complete, your device is turned off
automatically. To turn on your device, press the Power/Lock key.

Tip: If you are planning to give away or recycle your device,
remember to also remove your micro SIM card and media card.
